To allwkomit mag/concern:

Be it known that I, HARoLn'M. SCHEIBE, a citizen of the;United' States, and a resident. of Wilkinsbu'r in the county of Allegheny and State 0 Pennsylvania, have invented a new and useful Improvement in Vapor Electrical Apparatus, of which the following is a specification. v i My ineiention relates to-vapor .electrical apparatus, and it has for its object to provide a means for automatically starting 'v'aor rectifiers and similar devices that shall e simple in construction and reliable .in.

operation. a r a The single .figure of the accompanying of distribution embodying my invention.

. Referring to the drawing, alternating'current energy is supplied to a vapor rectifier 1.;

. from any suitable source, such as supply Oil? cuit -2-3, through a reactance 4, regulating dials 5 and 6 and a transformer 7. Regu; lating dials 5 and 6 are'adapted to so vary the circuit connection of the transformer as to adjust the alternating current voltage impressed upon the rectifier.- The rectifier 1 comprises a substantially cruciform bulb 8, a sup orting frame 9 therefor, which is pivota ly mounted on a stationary shaft 10,

d a starting or tiltingma het. 11, a counter-- weight 11 and buffer sprlngs 12. The starting, magnet ll comprises stationary and -movable core members 13 and 14, and coils- 15,-16Qand17. The movable core member 14' 3 is connected-to a crank projection 13 on the frame 9 by means of a rod'1-9." The bulb 8 .lS provided'with alternating current terminals'20 and 21-, which are connected to the- 11. The coils 15 and 17 of the startlng mag-j net may be' connected either in multlple '-0r 'in series relatlon, across the circuit 23,'

{through a relay switch 27.' The terminals 'of the coil 16 are respectively;connectedto.

the auxiliary terminal 26 and thedirectcurrent terminal 24, so-that this coil is short circuited when the bulb tilted. The relay switch 27 comprises stationar "and movable co emembers 28 and 29, acoil 30 anda closing sprin '31. The coil 30 is; connectedvin series wit the direct current circuit of the rectifier which is jointed "to-the middle point of the transformer 7 in the usualmanner.

When ener ized, the relay switch 27 is open and the coi s 15 and 17 are deenergi'zed.

The operation of the device is as follows: Assuming that the rectifying process is in operation so'thatthe coil 30 1s energized,

*and' the relay switch 27 is open; the bulb will occupy'.1tsnormal position so that the coil 16 is denergized' and, sincethe relay switch 27 is open, the coils 15 and'17 will alsorybe de'elnergized. Should the alternating cur ent supply, circuit 23 be interrupted, or shouldlthe rectifying process-be stopped, for any reason, the direct current traversing the circuit conductors 25 will, of course, be interrupted and the coil 30 deenergized.

The s ring-31 will then close the switch 27 and a terna'ting current energy will be supplied from conductor 3 through conductor 32 to "coils-15 and 17, the circu t being completed through conductor 33 to the conducs tor 2'. When'the coils 15'and 17 are energized, the bulb 8 will be tilted and the coil 16 will be short-circuited, as 'above indicated. The coil 16 acts like a short circuited secondary winding of a transformer since the coils 15, 16 and 17 are mounted on the same .core members and, therefore, the magnetization effected by the "coils'15 and .17 will be partially neutralized by the coil 16 when the then brin the rectifier to its olperating position an -an arc will be pro uced w'ithin the'bulb by the interruption of the short cir- (suit/above indicated, and the rectifying process may be recommenced. If the rectifier fails to start, the coils 1-5 and 17 will remain energized, so that the starting process will 'be repeated until the coil 30 is energlzed by the startingof the rectifier.

p The circuit connections of the coils 15, 16 and 17 are such that the rectlfymg processpleted through t e vapor supplying unidibut, if, for any reason, the current is supplied .through auxiliary terminal 26, the coil 16 Twill be so energized by the unidirectional current as to again tilt the-bulb.

It will. belreadily understood that my ulb is tilted. The counter-weight 11; will -'rectional current through the termlnal 24,

tends to start pro erly with the'circuits coma mercury vapor rectifiers and that it may be employed for starting other forms of vapor electrical apparatus, such as vapor lamps.

I claim as my' invention:

1. A starting or tilting magnet for vapor electric apparatus comprising an actuating coil or 0011s and an opposin coil which is efi'ective when the apparatus 1s tilted.

2. A starting or tilting magnet for vapor electric apparatus comprising stationary and movable core members, an actuating coil en circling the core members and anoppo sing coil in inductive relation thereto which is short circuited when the apparatus is tilted.

ive relation thereto which is short circuited by' the'liquid in the bulb when the frame is tilted;

4. In vapor electric apparatus, the combination with a pivotally mounted sup orting frame, and a rectifier bulb having al ing current terminals, a direct current terminal and an auxiliary terminal, of a starting or tilting magnet for the frame comprising stationary and movable core members, actuating coils therefor, and an'opposing coil in inductive relation thereto, the respective terminals of the opposing 0011 being connected to the direct current terminal and to the auxiliary terminal of the rectifier.

In testimony whereof, I have hereunto ternatsubscribed my name this 13th day of J anu- 40 ary, 1909.
